Thanks for the respond Steven, Yes, I did execute it from a terminal in the desktop environment.
I have un-checked "Available to all users" for my active network connection, but, the "mount: / is busy" message still appears. So, I think my problem is not with the network manager. So, as you suggested, I added: /bin/ps > /DEBUG /usr/bin/lsof >> /DEBUG to /etc/init.d/umountroot before the 'mount -n -o remount,ro /' sequence. And you can see the out put in the attachment. This time, I input the 'ps -ef and losf -nP' command not from terminal but from tty1. Was that what you meant? Or how is it to reproduce the output you meant? ** Attachment added: "umountroot, ps -ef, & lsof -nP output" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/963106/+attachment/3187427/+files/umountroot%2Cps%20-ef%2C%20%26%20lsof%20-nP%20output.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/963106 Title: NetworkManager causes orphaned inodes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/963106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
